ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 635,327, dated October24, 1899. Application led May l, 1899. Serial No. 715,169. (No model.)

To @ZZ whom, t may concern:

Be it known that we, KARL KPPERS and HEINRICH SCHROEDER, citizens of theKingdom of Prussia, and residents of Aachen, in the Kingdom of Prussia,German Empire, have invented certain new and useful Improvements inGenerators for Acetylene Gas, of which the following is a specification.

The object of the present invention is an automatically-operatinggenerator for acetylene gas, in which small quantities of carbid aresuccessively thrown into the water.

The apparatus is provided with a device for measuring the quantity ofcarbid consumed without dismounting the whole.

In the accompanying drawings, Figure l shows a vertical section throughthe axis of the apparatus. Fig; 2 shows the measuring device inelevation and on an enlarged scale. Fig. 3 is. the same as seen fromabove.

The receiver for the carbid a, closed tightly at its top, has at itslower end an opening ordinarily closed by a clack-valve e, the movementsof which are controlled from au annular iioat g by means ofconnecting-rods f. The receiver a is fastened tightly by means ofscrew-bolts passed through a flange o to a cylinder c, which opens belowinto the vessel d, imitating the form of a divers bell and which isinserted into another vessel m filled to a certain height with water. .Iust below the valve e there is arranged a funnelshaped tube h fordirecting the carbid to the central opening of the iioat and to impedethe scattering of the same. In the top of the bell-shaped vessel d isarranged a gas-pipe i, from which a stop-cock Z leads to the cleaner. Asecond pipe n leads from the top of the receiver to the same stop-cock.Differences in the internal pressure in the apparatus are avoided bymeans of these two pipes.

On the top of thereceiver is arranged a vertical glass tube, in whichrests a met-al rod ending in a disk or a ball. This rod is engaged bythe curved end of a second rod arranged horizontally and fixed with itsfree end to a curved metallic membrane r. Ordinarily the membrane iscurved and the hook engaging the metallic rod presses the same againstthe walls of the tube, thereby preventing it from sliding downward. Inorder to measure the quantity of carbid consumed, the membrane isslightly pressed against. Then the hook lets go the rod and it slidesdown until the disk reaches the surface of the carbid contained in thereceiver.

The receiver is charged with granulated carbid, which may be mixed withsand. The vessel m is filled with water. On opening the cock Z the waterbegins to rise in the inner vessel d. The iioat also begins to rise, andthe valve e is opened by means of the connecting-rod f. A quantity ofcarbid falls through the funnel into the water, and the generation ofgas begins. By the accumula- Lionof gas in I[he receiver the level ofthe water is depressed, and the float g sinks and shuts the valve e. Assoon as the quantity of gas diminishes, the same play begins anew. Thevalve s leads to a pressure-indicator.

The mud formed by the operation of the apparatus falls down into thefunnel-shaped bottom of the outer vessel m, from where it may easily beremoved by means of a flexible hose..

A pipe t is passed through the top of the vessel d and carried down withits lower end near the bottom of said vessel. It serves as a safetydevice for the escapement of gas, if in case of a breakdown theapparatus does not work well.

What we claim is-Y An automatically-operating generator for acetylenegas, consisting in a vessel imitating the form of a divers bell, to theIfop of which is fixed, by means of a tube, a receiver for the carbid,open at its bottom; said opening being controlled by a clack-valve,actuated by means of an annular iloat in the bellshaped vessel, saidvessel resting in another one, the bottom of which is funnel-shaped andprovided at its lower end with a flexible hose for the purpose ofremoving the mud; pipes arranged in the top of the receiver and Intestimony whereof We affix our signa- Icures in presence of twowitnesses.
